Electrical Wiring

First house lighting systems are single phase not three phase. To connect a generator to the house lighting system for emergency power, it would take an electrician to do the job properly. The biggest concern would be to isolate the rest of the service from the main distribution supply service and then isolate the rest of the distribution panel loads from the lighting loads.

Grounding of I and C? to ground something is to have a wire that goes to a grounded connection the bare wire in a normal wire set.

you can call the manufacture who made the equipment with a model number and serial number of that particular piece of equipment. for example in blower assembly or ac unit

I found this one. I have a ton at my home. They're not uncommon.

In electrical engineering, a safety device that protects electric circuits from the effects of excessive electric currents.

A fuse commonly consists of a current-conducting strip or wire of easily fusible metal; whenever the circuit is made to carry a current larger than that for which it is intended, the strip melts to interrupt it.

I do not believe any lighting fixtures of any voltage have ever been made to work off of three-phase circuits. Light Fixtures are always single-phase 2-wire circuits In the USA the standard voltages for branch circuits are: 120, 208, 240, 277 or 480 The light fixture must be rated to match whichever field voltage is being used. Some light fixtures are made multi-rated so they can be used on more than one circuit voltage

A large rubber band spins, rubbing on a metallic dome. some electrons are transfered from the band to the dome, acting as static electricity. When, say Steve, touches the dome the charged particles will leap to him. Steve will experience a static shock.

if we r talking about the power that is generated in powerhouses( i.e, source is not a D.C battery), one of the two terminals that comes out of the dynamo(of generator) is grounded near the generating plant itself. so theoretically speaking, ground and neutral are at same potential. so voltage diff between them would be 0.

but practically, ground is a term given to terminal that connects body of electrical appliance at home or industry directly into earth. this is done to prevent electrocution of any person handling it, just in case the body of appliance comes into contact with a live wire within the instrument(may be due to faulty wiring or normal wear and tear) and with probably defective neutral contact. Even in case of such a happening, if there is proper grounding, the voltage diff between them is 0.

You can't. You must supply the motor with it's required voltage. If it's a dual voltage motor, follow the wiring schematic on the motor nameplate to switch from low to high voltage.

A soldered joint that was done poorly.

If secondary side of the 3 phase transformer has any issue, it would result unbalanced voltage between phases. Other reason could be if the load on one phase is highly different than other phase, it also would result in unbalanced voltage.

That is a formidable project.

To control fingers, most likely you should use something like miniature linear motors. The position controls become more of a problem, since you would need to use microcontrollers, analog to digital converters and feedback loops to detect position.

It would be best if you didn't bite off such a big project until after you've learned some of the basics.

good luck.

Yes, Pyrite can conduct electricity.

Y Pb Pr cables are identical to those used for YUV, Y Cb Cr and RGB cables. They are therefore completely interchangeable. YUV and YPbPr signals are both referred to as component signals although the precise format of the signals are different. The interface is the same for each, namely three wires. The standard cable is a 75 Ohm co-ax cable terminated in RCA plugs for domestic equipment and BNC connectors for commercial equipment. It is always worth using good quality cable to avoid losses in the signal. RGB uses the same three wires but the signal is separated into three separate colors. Normally, an RGB signal will have additional cables for synchronisation signals so an RGB interface will often have 4 or 5 connectors.

A switch is installed in a circuit to stop the current flow. Without the switch there is no way to disconnect the operation of the circuit's load. In modern households the switch is a convenient way to control room lighting from a convenient location. Without switches the circuit power would have to be controlled from the service distribution panel's breakers. In this scenario the breaker would be in the same class as a switch.

It is a variable resistance.

As you turn the volume control from low to high - or press buttons to do the same thing on miniature electronic items like mobile phones and MP3 players - the resistance of the volume control is reduced so that a higher current carrying audio waves can get through to the amplifier and so to the item's loudspeaker or headphones.

A metal is a shiny element that conducts electricity and heat.

Overhead power lines are insulated from ground, typically using strings of glass or ceramic insulators. The wire itself is bare, though - it does not have insulation on it. There are many different types of overhead power line, but I'm not aware of any that actually have insulation.

Higher than normal demand will cause more electrons to flow through the load. This will cause the amperage to increase, thereby causing power to increase. A lightning strike on the primary line will cause this condition.

Very unlikely. Its 3 phase for a reason, it needs a large voltage/current to power it, single phase won't provide that.

Most likely a defective phase winding in the motor or even a missing phase in your power input.
